PLC Controlled System

I would be interested in your PLC project files. What was the reason for your stuck mashes?

I'll upload them soon, I don't know if or how well I'll be able to attach a zip file to this thread though.

I think it got stuck because to pump flow was too high. Im only using a small dc pump with a cheap pwm circuit which I got off ebay to control the speed. Once you turn the speed anywhere below 75%, the flow seems to stop. I did throttle the flow a bit as well which helped but I was too worried about the heating element being run dry to walk away and leave it. I suppose if I used a 230v motor with a proper speed controller, this would over come it but that's more expense. The addition of a grain bag solved it funnily enough and it gave me more control over the grains. Never any grains in the final wort and the grain bag acts as a great recirculation filter.

As suspected, it won't let me attach the zip file. Any ideas?

Here's a link to download the programming software. It's free but you do have to sign up.

You could use something like Dropbox. Just upload the files to Dropbox and then share the link.
